Abstract
Rationale: Limited data exist on the safety and effectiveness of elexacaftor-tezacaftor-ivacaftor (ETI) in people with cystic fibrosis (pwCF) and advanced lung disease. Objectives: To evaluate the effects of ETI in an unselected population of pwCF and advanced lung disease. Methods: A prospective observational study, including all adults aged 18 years and older with percentage predicted forced expiratory volume in 1 second (ppFEV1) ⩽ 40 who initiated ETI from December 2019 to June 2021 in France, was conducted. PwCF were followed until August 8, 2022. Results: ETI was initiated in 434 pwCF with a median ppFEV1 of 30 (interquartile range, 25-35), including 27 with severe cystic fibrosis liver disease and 183 with diabetes. PwCF were followed for a median of 587 (interquartile range, 396-728) days after ETI initiation. Discontinuation of ETI occurred in 12 (2.8%) pwCF and was due mostly to lung transplantation (n = 5) or death (n = 4). Absolute increase in ppFEV1 by a mean of +14.2% (95% confidence interval, 13.1-15.4%) occurred at 1 month and persisted throughout the study. Increase in ppFEV1 in the youngest age quartile was almost twice that of the oldest quartile (P < 0.001); body mass index < 18.5 kg/m2 was found in 38.6% at initiation versus 11.3% at 12 months (P = 0.0001). Increases in serum concentrations of vitamins A and E, but not 25-hydroxy vitamin D3, were observed. Significant reductions in the percentages of pwCF using oxygen therapy, noninvasive ventilation, nutritional support, and inhaled and systemic therapies (including antibiotics) were observed; insulin was discontinued in 12% of patients with diabetes. Conclusions: ETI is safe in pwCF and advanced lung disease, with multisystem pulmonary and extrapulmonary benefits.

[PMID: 38309533 DOI: 10.1016/j.diabres.2024.111124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 01/25/2024] [Accepted: 01/29/2024] [Indexed: 02/05/2024]
Abstract
AIMS The diagnosis of cystic fibrosis-related diabetes (CFRD) faces several challenges. We propose a novel screening algorithm to alleviate the burden of cystic fibrosis (CF). METHODS Through a retrospective cross-sectional single-centre study, HbA1c and HOMA2 indices were assessed in multiple models as alternative diagnostic tools from OGTT data. We sought to establish specific thresholds for CFRD screening with oral glucose tolerance test (OGTT) as gold standard. We evaluated various straightforward or sequential approaches, in terms of diagnostic accuracy while also quantify the potential reduction in OGTTs through these different methods. RESULTS HOMA indices were recovered in 72 patients. We devised a composite index that combines HbA1c and HOMA-B: Diabetes Predicting Index in cystic fibrosis (DIPIc) = (HbA1c(%) × 3.455) - (HOMA-B(%) × 0.020) - 19.294. This index yields the highest screening accuracy according to receiver-operating characteristics curves. Using a stepwise algorithm that incorporates DIPIc decreases the requirement for annual OGTTs. A CFRD exclusion cutoff less than -1.7445 (sensitivity 98 %), in conjunction with a CFRD diagnostic threshold greater than 0.4543 (specificity 98 %) allows for 71 % OGTT sparing. CONCLUSION The composite index DIPIc is a suitable, less invasive screening method for CFRD, which enables to avoid many OGTTs.

Abstract
This paper delineates several aspects of cystic fibrosis-related diabetes (CFRD)-a common complication of cystic fibrosis (CF). CFRD exhibits a predilection for older individuals with CF, yet it also extends its influence on children and adolescents. Scientific insights postulate a potential link between CFRD and the aberrant mucus production within the pancreas, thereby culminating in pancreatic insufficiency. This, in turn, perturbs the synthesis of insulin, a pivotal endocrine hormone responsible for the regulation of glycemic levels. Standardized protocols advocate for the systematic screening of CFRD among all individuals with CF, commencing at the age of 10 years using the oral glucose tolerance test (OGTT). Therapeutic modalities encompass insulin therapy, dietary adjustments, and the vigilant monitoring of glycemic parameters. The overarching objective is to maintain blood glucose levels within a targeted range to mitigate the advent of diabetic complications. Untreated or sub-optimally managed CFRD can precipitate a spectrum of deleterious health ramifications, encompassing cardiovascular afflictions, neuropathy, renal dysfunction, and ocular complications.

Understanding and addressing the needs of people with cystic fibrosis in the era of CFTR modulator therapy. THE LANCET. RESPIRATORY MEDICINE 2023; 11:916-931.

Abstract
Cystic fibrosis is a multiorgan disease caused by impaired function of the cystic fibrosis transmembrane conductance regulator (CFTR). Since the introduction of the CFTR modulator combination elexacaftor-tezacaftor-ivacaftor (ETI), which acts directly on mutant CFTR to enhance its activity, most people with cystic fibrosis (pwCF) have seen pronounced reductions in symptoms, and studies project marked increases in life expectancy for pwCF who are eligible for ETI. However, modulator therapy has not cured cystic fibrosis and the success of CFTR modulators has resulted in immediate questions about the new state of cystic fibrosis disease and clinical challenges in the care of pwCF. In this Series paper, we summarise key questions about cystic fibrosis disease in the era of modulator therapy, highlighting state-of-the-art research and clinical practices, knowledge gaps, new challenges faced by pwCF and the potential for future health-care challenges, and the pressing need for additional therapies to treat the underlying genetic or molecular causes of cystic fibrosis.

Abstract
Cystic fibrosis (CF) is a genetic disease caused by mutations in the gene encoding for the ion channel cystic fibrosis transmembrane conductance regulator (CFTR). The management of CF disease has evolved in recent decades from treating downstream disease manifestations affecting the airways, the lungs and the gastrointestinal system to addressing the CFTR gene defect. The advent of CFTR modulators, which correct the functionality of the defective CFTR, contributes to reshaping the landscape of CF demographics, prognosis and therapies, including nutritional management. A spectrum of clinical manifestations is emerging within the same patient population where undernutrition and nutritional deficiencies coexist with excessive weight gain and metabolic derangements. Such contrasting presentations challenge current practices, require adjustments to traditional approaches, and involve more individualised interventions. This narrative review examines the current state of knowledge on the nutritional management of people living with cystic fibrosis from early life to adulthood in the era of CFTR modulation.
